This Wednesday on January 9, Duchess Catherine will ring in her 37th birthday.

There's no doubt the mother-of-three will be surrounded by her nearest and dearest including children Prince George, five, Princess Charlotte, three, and youngest son Prince Louis, eight months.

But it appears there'll be one key person missing for part of the celebrations - her husband, Prince William.

This will be the first time in six years the royal couple have spent some of her birthday apart as it's been confirmed by Kensington Palace the Duke of Cambridge, 36, has already committed to an official engagement at the Royal London Hospital in east London for an event for the 30th anniversary of London's Air Ambulance on the same day as Kate's birthday.

"The Duke of Cambridge will visit @LDNairamb on Wednesday 9th January to recognise the work that their first responders carry out delivering life-saving treatment across London," the palace's official tweet explained.
